If you must install a rear-facing child re-
straint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the
59indicator lamp is illumi-
nated, indicating that the front passen-
ger front air bag is deactivated. Should
the 59 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation. Peri-
odically check the 59 indi-
cator lamp while driving to make sure
the lamp is illuminated. If the
59indicator lamp goes out
or remains out, do not transport a child
on the front passenger seat until the
system has been repaired. A child in a
rear-facing child restraint on the front
passenger seat will be seriously injured
or even killed if the front passenger front
air bag inflates.
If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and se-
cure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activat-
ed (
page 85).
Warning!
G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs until they reach a
height where a lap/shoulder belt fits proper-
ly without a booster.

If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to
do so, make sure that the
59 indicator lamp is illumi-
nated, indicating that the front passen-
ger front air bag is deactivated. Should
the 59 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation. Peri-
odically check the 59 indi-
cator lamp while driving to make sure
the 59 indicator lamp is il-
luminated. If the 59 indica-
tor lamp goes out or remains out, do not
transport a child on the front passenger
seat until the system has been repaired.
A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front pas-
senger front air bag inflates.
If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and se-
cure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
air bag may or may not be activated
(page 85).
iDeployment of the driver front air bag
does not mean that the front passenger
front air bag also should have de-
ployed.
The Occupant Classification System
(page 85) may have determined:
that the seat was empty or occu-
pied by the weight up to or less than
that of a typical 12-month-old child
seated in a standard child restraint
– both instances where the system
suppresses deployment of the front
passenger front air bag even
though the impact met the criteria
and was of sufficient severity to de-
ploy the driver front air bag
that the seat was occupied by a
small individual (such as a young
teenager or a small adult) or a child
weighing more than the weight of a
typical 12-month-old child in a stan-
dard child restraint – instances
where the system may suppress
deployment of the front passenger
front air bag even though the
impact met the criteria and was of
sufficient severity to deploy the
driver front air bag
